TIN Number Application and Search

A Tax Identification Number (TIN Number) is an 11-digit identifier assigned to dealers in India. It's similar to a VAT Number and CST Number, as the old sales tax and CST numbers issued by State Sales Tax Authorities have been replaced by TIN. It is mandatory to mention the TIN number when undertaking state-level or inter-state sales, and dealers must list their TIN in all sales and purchase transactions. Let’s explore the procedure of TIN Number Application in India and the process for searching a TIN Number.

Apply for TIN Number

A TIN Number is essential for dealers involved in manufacturing or trading goods in India, where VAT (Value Added Tax) is applicable. VAT is levied on the value added to a product at each production stage. Under the VAT regimen, the end consumer bears the VAT burden, while registered dealers can avail input credit, allowing them to deduct VAT payments made during purchases from VAT collected during sales. Consequently, dealers pay VAT only on the value increment they add.

VAT is state-implemented according to guidance from the Empowered Committee, meaning VAT rates, registration procedures, return filing requirements, and due dates vary by state. Entrepreneurs must familiarize themselves with their state's VAT or TIN Registration procedures and comply with regulations set by local authorities.

To apply for a VAT or TIN Number, entrepreneurs usually need to provide documents like premises proof (Electricity Bill, Property Tax Receipt, Rental Agreement, etc.), PAN card, bank statement, MOA/AOA, photos of promoters, promoters' address proof, business nature, and other details. Documentation requirements differ across states, so checking with the State's Sales Tax Department is crucial for understanding the TIN Application process.

Once allotted, a TIN Number registers dealers, permitting them to legally engage in goods sales. The TIN issued by State Sales Tax Authorities must be included in all company invoices and sometimes disclosed to sellers. TIN Numbers remain valid indefinitely but can be recalled if periodic returns are not filed.

Dealers often verify TIN Numbers online via https://www.tinxsys.com, where they can search the TIN database across India for dealer information and registration status. For more information on return filing and deadlines, visit our section on GST due dates.
